Nansen rolls out search tool for more than 200,000 FOMO-linked wallets on Solana and Base

Nansen has launched a new search feature that covers more than 200,000 wallets linked to FOMO across Solana and Base, adding another layer of visibility into activity tied to the mobile copy-trading app. Users can look up holdings, transaction records, and profit or loss data for those wallets, according to the announcement cited by Odaily. The feature also includes linked addresses that are not visible inside the FOMO app interface itself, widening the range of wallets that can be tracked through Nansen’s database. Nansen said its database has already labeled more than 500 million wallets. The report also outlined key details about FOMO: the non-custodial copy-trading platform went live around May 2025 and supports gas-free swaps across multiple chains. Since launch, its cumulative trading volume has reached the billions of dollars. The report added that FOMO’s weekly revenue once hit $264 million in 2026, and that the company completed a $75 million Series B round in June, bringing total funding to about $94 million.
